Di-μ-ethano­lato-bis­[diethano­lato(2-methyl­quinolin-8-olato)titanium(IV)]

In the centrosymmetric dinuclear title compound, [Ti2(C10H8NO)2(C2H5O)6], the Ti atom is bonded to an N,O-bidentate quinolin-8-olate ligand, two terminal ethano­late anions and two bridging ethano­late anions in a distorted TiNO5 octa­hedral geometry. An intra­molecular C—H⋯O hydrogen bond occurs; in the crystal, inter­molecular C—H⋯O inter­actions help to establish the packing

Tris(diisopropyl­ammonium) hydrogensulfate sulfate

The cations and anions of the title salt, 3C6H16N+·HSO4 −·SO4 2−, are linked by N—H⋯O and O—H⋯O hydrogen bonds into a three-dimensional network. The hydrogensulfate ion, with a single S—O(H) bond of 1.563 (2) Å, forms a short O—H⋯O hydrogen bond [O⋯O = 2.609 (2) Å] to the sulfate ion. The hydrogensulfate ion accepts two hydrogen bonds from two cations, whereas the sulfate ion, as an acceptor, binds to four cations. The sulfate ion is disordered approximately equally over two sites related by rotation around one of the O—S bonds

Effects of Peer-education on Quality of Life in Adults with Type 2 Diabetes

Aims: Diabetes is the most prevalent metabolic disease in human being. Self-care is the most important way of preventing complications. This study aimed at investigating the effects of peer-education on quality of life in adult patients with type 2 diabetes. Materials & Methods: This semi experimental study was conducted at a diabetes clinic affiliated to Gonabad University of medical sciences, Iran in 2017 among 80 patients with type 2 diabetes. Patients were selected based on available sampling method, and they were randomly divided into two groups, namely intervention and control (40 patients each group). The data of all patients were collected by demographic and disease information questionnaire and diabetic patient quality of life (QOL) questionnaire. The present study was carried out in three main steps: In the first step (before intervention), peers were trained by the researcher during four sessions. In the second step (intervention), quality of life of patients was assessed before training; then, patients in intervention group were trained and instructed during three sessions; the control group received the usual instruction, too. In the third step (one month later), quality of life of patients in both groups was assessed. The data were analyzed by SPSS statistics software Version 20, using Chi-square, Fisher, independent t test, paired t test, Mann-Whitney U, and Wilcoxon. Findings: The mean scores of quality of life in intervention group did not have any significant difference with control group before instruction (p>0.05). After instruction, the mean scores of quality of life in the intervention group compared with the control group increased significantly (p<0.001). Conclusion: Peer education improves quality of life in adult patients with type 2 diabetes

(1-Naphthyl­meth­yl)ammonium chloride

The reaction of 1-naphthyl­methyl­amine and hydro­chloric acid in a 1:1 molar ratio resulted in the formation of the 1:1 proton-transfer compound, C11H12N+·Cl−. In the crystal, the ions are linked by N—H⋯Cl hydrogen bonds into a sheet pattern in the ab plane such that each Cl− ion is bonded to three NH groups from the naphthylmethylammonium ion

catena-Poly[[diphenyl­propyl­tin(IV)]-μ-chloroacetato-κ2 O:O′]

The title compound, [Sn(C3H7)(C6H5)2(C2H2ClO2)]n, comprises polymeric carboxyl­ate-bridged spiral chains with two monomer formula units in the asymmetric unit. Both Sn centres exhibit similar distorted trigonal–bipyramidal [C3SnO2] coordination, with the O atoms of the carboyxlate ligands in trans positions

The supramolecular effect of aromaticity on the crystal packing of furan/thiophene carboxamide compounds

N-2-pyrazinyl-2-furancarboxamide (I) and N-2-pyrazinyl-2-thiophenecarboxamide (II) are compounds containing different five-membered heteroaromatic rings, furan and thiophene, respectively. They were designed and synthesized to examine the effect of an increase in aromaticity from furan to thiophene on the crystal packing. In order to explore the various features of the crystal packing motifs in more detail, single crystal X-ray diffraction, Hirshfeld surface analysis and theoretical calculations were carried out on the two compounds. The results clearly show that the heteroatom substitution of O to S in five-membered rings led to an increase in the effectiveness of π-based interactions in II, whereas hydrogen bond interactions play a more important role in the stabilization of the supramolecular architecture of I
